Changelog

Tomcat 9.0.0.M9

Catalina

  • Fix: 18500: Add limited support for wildcard host names and host aliases. Names of the form *.domainname are now permitted. Note that an exact host name match takes precedence over a wild card host name match. (markt)
  • Fix: 57705: Add debug logging for requests denied by the remote host and remote address valves and filters. Based on a patch by Graham Leggett. (markt)
  • Fix: Correct a regression in the fix for 58588 that removed the entire org.apache.juli package from the embedded JARs rendering them unusable. (markt)
  • Add: 59399: Add a new option to the Realm implementations that ship with Tomcat that allows the HTTP status code used for HTTP -> HTTPS redirects to be controlled per Realm. (markt)
  • Fix: 59708: Modify the LockOutRealm logic. Valid authentication attempts during the lock out period will no longer reset the lock out timer to zero. (markt)
  • Update: Change the default of the sessionCookiePathUsesTrailingSlash attribute of the Context element to false since the problems caused when a Servlet is mapped to /* are more significant than the security risk of not enabling this option by default. (markt)
  • Fix: Follow-up to 59655. Improve the documentation for configuring permitted cookie names. Patch provided by Kyohei Nakamura. (markt)
  • Fix: Do not attempt to start web resources during a web application's initialisation phase since the web application is not fully configured at that point and the web resources may not be correctly configured. (markt)
  • Fix: Improve error handling around user code prior to calling InstanceManager.destroy() to ensure that the method is executed. (markt)

Coyote

  • Fix: Fix a cause of multiple attempts to close the same socket. (markt)
  • Code: Refactor the certifcate keystore and trust store generation to make it easier for embedded users to inject their own key stores. (markt)
  • Update: Add a maxConcurrentStreamExecution on the HTTP/2 protocol handler to allow restricting the amount of concurrent stream that are being executed in a single connection. The default is to not limit it. (remm)
  • Add: 59233: Add the ability to add TLS virtual hosts dynamically. (markt)
  • Fix: Correct a problem with ServletRequest.getServerPort() for secure HTTP/2 connections that meant an incorrect value was retured when using the default port. (markt)
  • Fix: Improve error handling around user code prior to calling InstanceManager.destroy() to ensure that the method is executed. (markt)

Jasper

  • Fix: Improve error handling around user code prior to calling InstanceManager.destroy() to ensure that the method is executed. (markt)

WebSocket

  • Code: Now the WebSocket implementation is not built directly on top of the Servlet API and can use Tomcat internals, there is no need for the dedicated WebSocket Executor. It has been replaced by the use of the Connector/Endpoint provided Executor. (markt)
  • Fix: Improve error handling around user code prior to calling InstanceManager.destroy() to ensure that the method is executed. (markt)

Web Applications

  • Fix: Do not log an additional case of IOExceptions in the error handler for the Drawboard WebSocket example when the root cause is the client disconnecting since the logs add no value. (markt)
  • Fix: 59642: Mention the localDataSource in the DataSourceRealm section of the Realm How-To. (markt)
  • Fix: 59672: Update the security considerations page of the documentation web application to take account of the fact that the Manager and HostManager applications now have a RemoteAddrValve configured by default. (markt)
  • Fix: Follow-up to the fix for 59399. Ensure that the new attribute transportGuaranteeRedirectStatus is documented for all Realms. Also document the NullRealm and when it is automatically created for an Engine. (markt)
  • Fix: Fix the description of maxAge attribute in jdbc-pool doc. This attribute works both when a connection is returned and when a connection is borrowed. (kfujino)
  • Fix: 59774: Correct the prefix values in the the documented examples for configuring the AccessLogValve. Patch provided by Mike Noordermeer. (markt)

Tribes

  • Add: Add log message when the ping has timed-out. (kfujino)

2016-06-13 Tomcat 9.0.0.M8

Coyote

  • Fix: Remove accidentally committed debug code. (markt)

not released Tomcat 9.0.0.M7

Catalina

  • Fix: RMI Target related memory leaks are avoidable which makes them an application bug that needs to be fixed rather than a JRE bug to work around. Therefore, start logging RMI Target related memory leaks on web application stop. Add an option that controls if the check for these leaks is made. Log a warning if running on Java 9 with this check enabled but without the command line option it requires. (markt)
  • Fix: Ensure NPE will not be thrown during deployment when scanning jar files without MANIFEST.MF file. (violetagg)
  • Code: Remove the clearReferencesStatic option from StandardContext. It was known to cause problems with some libraries (such as log4j) and was only linked to suspected memory leaks rather than known memory leaks. It had been disabled by default with no increase in the reports of memory leaks for some time. (markt)
  • Fix: 59604: Correct the assumption made in the URL decoding that the default platform encoding is always compatible with ISO-8859-1. This assumption is not always valid, e.g. on z/OS. (markt)
  • Fix: 59608: Skip over any invalid Class-Path attribute from JAR manifests. Log errors at debug level due to many bad libraries. (remm)
  • Fix: Fix error message when failed to register MBean. (kfujino)
  • Fix: 59655: Configure the cookie name validation to use RFC6265 rules by default to align it with the default cookie parser. Document the impact system properties have on cookie name validation. (mark)

Coyote

  • Fix: Ensure that requests with HTTP method names that are not tokens (as required by RFC 7231) are rejected with a 400 response. (markt)
  • Fix: When an asynchronous request is processed by the AJP connector, ensure that request processing has fully completed before starting the next request. (markt)
  • Fix: Improve handling of HTTP/2 stream resets. (markt)
  • Add: 58750: The HTTP Server header is no longer set by default. A Server header may be configured by setting the server attribute on the Connector. A new Connector attribute, serverRemoveAppProvidedValues may be used to remove any Server header set by a web application. (markt)
  • Fix: 59564: Correct offset when reading into HTTP/2 input buffer that could cause problems reading request bodies. (violetagg/markt)
  • Fix: Modify the handling of read/write timeouts so that the appropriate error handling (ReadListener.onError(), WriteListener.onError() or AsycnListener.onError()) is called. (markt)
  • Fix: If an async dispatch results in the completion of request processing, ensure that any remaining request body is swallowed before starting the processing of the next request else the remaining body may be read as the start of the next request leading to a 400 response. (markt)

Jasper

  • Fix: 59567: Fix NPE scanning webapps for TLDs when an exploded JAR has an empty WEB-INF/classes/META-INF folder. (remm)
  • Fix: Fix a memory leak in the expression language implementation that caused the class loader of the first web application to use expressions to be pinned in memory. (markt)
  • Fix: 59654: Improve error message when attempting to use a TLD file from an invalid location. Patch provided by Huxing Zhang. (markt)

WebSocket

  • Fix: 59659: Fix possible memory leak in WebSocket handling of unexpected client disconnects. (markt)

Web applications

  • Fix: 58891: Update the SSL how-to. Based on a suggestion by Alexander Kjäll. (markt)

Extras

  • Code: 58588: Remove the JULI extras package from the distribution. It was only useful for switching Tomcat's internal logging to log4j 1.2.x and that version of log4j is no longer supported. No additional Tomcat code is required if switching Tomcat's internal logging to log via log4j 2.x. (markt)

jdbc-pool

  • Fix: Fix a memory leak with the pool cleaner thread that retained a reference to the web application class loader for the first web application to use a connection pool. (markt)

Other

  • Update: Update the internal fork of Commons DBCP 2 to r1743696 (2.1.1 plus additional fixes). (markt)

  • Fix: 59310: Do not add a Content-Length: 0 header for custom responses to HEAD requests that do not set a Content-Length value. (markt)
  • Fix: When normalizing paths, improve the handling when paths end with /. or /.. and ensure that input and output are consistent with respect to whether or not they end with /. (markt)
  • Fix: 59317: Ensure that HttpServletRequest.getRequestURI() returns an encoded URI rather than a decoded URI after a dispatch. (markt)
  • Fix: Use the correct URL for the fragment when reporting errors processing a web-fragment.xml file from a JAR located in an unpacked WAR. (markt)

  • Fix: 58629: Allow an embedded Tomcat instance to start when the Service has no Engine configured. (markt)
  • Fix: Correctly notify the MapperListener associated with a Service if the Engine for that Service is changed. (markt)
  • Add: Make a web application's CredentialHandler available through a context attribute. This allows a web application to use the same algorithm for validating or generating new stored credentials from cleartext ones. (schultz)
  • Fix: 58635: Enable break points to be set within agent code when running Tomcat with a Java agent. Based on a patch by Huxing Zhang. (markt)
  • Fix: Fixed potential NPE in HostConfig while deploying an application. Issue reported by coverity scan. (violetagg)
  • Fix: 58655: Fix an IllegalStateException when calling HttpServletResponse.sendRedirect() with the RemoteIpFilter. This was caused by trying to correctly generate the absolute URI for the redirect. With the fix for 56917, redirects may now be relative making the sendRedirect() implementation for the RemoteIpFilter much simpler. This also addresses issues where the redirect may not have behaved as expected when redirecting from http to https to from https to http. (markt)
  • Fix: 58657: Exceptions in a Servlet 3.1 ReadListener or WriteListener do not need to be immediately fatal to the connection. Allow an error response to be written. (markt)
  • Fix: Correct implementation of validateClientProvidedNewSessionId so client provided session IDs may be rejected if validation is enabled. (markt)
  • Fix: 58701: Reset the instanceInitialized field in StandardWrapper when unloading a Servlet so that a new instance may be correctly initialized. (markt)
  • Update: Add a new flag aprPreferred to the Apr listener. if set to false, when using the connector defaults, it will use NIO + OpenSSL if tomcat-native is available, rather than the APR connector. (remm)
  • Fix: Add path parameter handling to HttpServletRequest.getContextPath(). This is a follow-up to the fix for 57215. (markt)
  • Fix: 58692: Make StandardJarScanner more robust. Log a warning if a class path entry cannot be scanned rather than triggering the failure of the web application. Includes a test case written by Derek Abdine. (markt)
  • Fix: 58702: Ensure an access log entry is generated if the client aborts the connection. (markt)
  • Fix: Fixed various issues reported by Findbugs. (violetagg)
  • Fix: 58735: Add support for the X-XSS-Protection header to the HttpHeaderSecurityFilter. Patch provided by Jacopo Cappellato. (markt)
  • Fix: Add the StatusManagerServlet to the list of Servlets that can only be loaded by privileged applications. (markt)
  • Fix: Simplify code and fix messages in org.apache.catalina.core.DefaultInstanceManager class. (kkolinko)
  • Fix: 58751: Correctly handle the case where an AsyncListener dispatches to a Servlet on an asynchronous timeout and the Servlet uses sendError() to trigger an error page. Includes a test case based on code provided by Andy Wilkinson.(markt)
  • Fix: Ensure that the proper file encoding if specified will be used when a readme file is served by DefaultServlet. (violetagg)
  • Fix: Fix declaration of localPort attribute of Connector MBean: it is read-only. (kkolinko)
  • Fix: 58766: Make skipping non-class files during annotation scanning faster by checking the file name first. Improve debug logging. (kkolinko)
  • Fix: 58836: Correctly merge query string parameters when processing a forwarded request where the target includes a query string that contains a parameter with no value. (markt/kkolinko)
  • Fix: Make sure that shared Digester is reset in an unlikely error case in HostConfig.deployWAR(). (kkolinko)
  • Add: Extend the feature available in the cluster session manager implementations that enables session attribute replication to be filtered based on attribute name to all session manager implementations. Note that configuration attribute name has changed from sessionAttributeFilter to sessionAttributeNameFilter. Apply the filter on load as well as unload to ensure that configuration changes made while the web application is stopped are applied to any persisted data. (markt)
  • Add: Extend the session attribute filtering options to include filtering based on the implementation class of the value and optional WARN level logging if an attribute is filtered. These options are available for all of the Manager implementations that ship with Tomcat. When a SecurityManager is used filtering will be enabled by default. (markt)
  • Code: Remove distributable and maxInactiveInterval from the Manager interface because the attributes are never used. The equivalent attributes from the Context always take precedence. (markt)
  • Fix: 58867: Improve checking on Host start for WAR files that have been modified while Tomcat has stopped and re-expand them if unpackWARs is true. (markt)
  • Fix: 58900: Correctly undeploy symlinked resources and prevent an infinite cycle of deploy / undeploy. (markt)

Coyote

  • Fix: 58621: The certificate chain cannot be set using the main certificate attribute, so restore the certificate chain property. (remm)
  • Fix: Allow a new SSL config type where a connector can use either JSSE or OpenSSL. Both could be allowed, but it would likely create support issues. This type is used by the OpenSSL implementation for NIOx. (remm)
  • Fix: Improve upgrade context classloader handling by using Context.bind and unbind. (remm)
  • Add: Improve OpenSSL keystore/truststore configuration by using the code from the JSSE implementation. (remm, jfclere)
  • Fix: Fix a potential loop when a client drops the connection unexpectedly. (markt)
  • Add: OpenSSL renegotiation support for client certificate authentication. (remm)
  • Fix: Fix NIO connector renegotiation. (remm)

Jasper

  • Fix: 57136#c25: Change default value of quoteAttributeEL setting in Jasper to be true for better compatibility with other implementations and older versions of Tomcat. Add command line option -no-quoteAttributeEL in JspC. (kkolinko)
  • Fix: Fix handling of missing messages in org.apache.el.util.MessageFactory. (violetagg)

Cluster

  • Fix: Enable an explicit configuration of local member in the static cluster membership. (kfujino)
  • Fix: Fix potential integer overflow in DeltaSession. Reported by coverity scan. (fschumacher)
  • Fix: In order to avoid that the heartbeat thread and the background thread to run Channel.heartbeat simultaneously, if heartbeatBackgroundEnabled of SimpleTcpCluster set to true, ensure that the heartbeat thread does not start. (kfujino)

WebSocket

  • Add: 55006: The WebSocket client now honors the java.net.java.net.ProxySelector configuration (using the HTTP type) when establishing WebSocket connections to servers. Based on a patch by Niki Dokovski. (markt)
  • Fix: 58624: Correct a potential deadlock if the WebSocket connection is closed when a message write is in progress. (markt)
  • Fix: 57489: Ensure onClose() is called when a WebSocket connection is closed even if the sending of the close message fails. Includes test cases by Barry Coughlan. (markt)

Web Applications

  • Fix: Correct some typos in the JNDI resources How-To. (markt)
  • Fix: Don't create session unnecessarily in the Manager application. (markt)
  • Fix: Don't create session unnecessarily in the Host Manager application. (markt)
  • Fix: 58723: Clarify documentation and error messages for the text interface of the manager to make clear that version must be used with path when referencing contexts deployed using parallel deployment. (markt)
  • Add: Document test.threads option in BUILDING.txt. (kkolinko)

Tribes

  • Fix: Ensure that the static member is registered to the add suspect list even if the static member that is registered to the remove suspect list has disappeared. (kfujino)
  • Fix: When using a static cluster, add the members that have been cached in the membership service to the map members list in order to ensure that the map member is a static member. (kfujino)
  • Fix: Add support for the startup notification of local members in the static cluster. (kfujino)
  • Fix: Ignore the unnecessary member remove operation from different domain. (kfujino)
  • Fix: Add support for the shutdown notification of local members in the static cluster. (kfujino)

General

  • Add: Make Java 8 the minimum required version to build and run Tomcat 9. (markt)
  • Update: Remove support for Comet. (markt)
  • Update: Tighten up the default file permissions for the .tar.gz distribution so no files or directories are world readable by default. Configure Tomcat to run with a default umask of 0027 which may be overridden by setting UMASK in setenv.sh. (markt)
  • Update: Remove native code (Windows Service Wrapper, APR/native connector) support for Windows Itanium. (markt)

Catalina

  • Update: The default HTTP cookie parser has been changed to org.apache.tomcat.util.http.Rfc6265CookieProcessor. (markt)

Coyote

  • Update: Remove support for the HTTP BIO and AJP BIO connectors. (markt)
  • Code: Refactor HTTP upgrade and AJP implementations to reduce duplication. (markt)
  • Add: Add support for HPACK header encoding and decoding, contributed by Stuart Douglas. (remm)
  • Add: 57108: Add support for Server Name Indication (SNI). There has been significant changes to the SSL configuration in server.xml to support this. (markt)
  • Add: Add SSL engine for JSSE backed by OpenSSL. Includes ALPN support. Based on code contributed by Numa de Montmollin and derived from code developed by Twitter and Netty. (remm)
  • Fix: RFC 7230 states that clients should ignore reason phrases in HTTP/1.1 response messages. Since the reason phrase is optional, Tomcat no longer sends it. As a result the system property org.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER is no longer used and has been removed. (markt)
  • Update: The minimum required Tomcat Native version has been increased to 1.2.2. The 1.2.x branch includes ALPN and SNI support which are required for HTTP/2. (markt)
